Beispielhaft genannt sind Verbindungen auf Basis von Latex, Natur- und Synthesekautschuk und andere synthetische Polymere auf Basis von Acrylaten, Methacrylaten, Polyurethanen, Polyolefine, Polyvinylderivaten, Polyestern, Polyamiden oder Silikonen. Depending on the application, the self-adhesive layer consists of different materials. Polymeric compounds of natural and synthetic origin are suitable. Compounds based on latex, natural and Synthetic rubber and other synthetic polymers based on acrylates, Methacrylates, polyurethanes, polyolefins, polyvinyl derivatives, polyesters, polyamides or silicones.
Besonders vorteilhaft zeigen sich hier die Acrylatsysteme auf Basis von Polymerisaten aus der Acrylsäure und deren Homologe, Derivate oder Reaktionsprodukten. Beispielsweise zeigten sich Co-Polymerisate auf Basis von 2-Ethylhexylacrylsäureester und n-Butylacrylat in Reaktion mit der Acrylsäure als vorteilhaft. Ferner ist es möglich, Harze oder Weichmacher dem Kleber zuzumischen. The acrylate systems based on polymers are particularly advantageous here from acrylic acid and its homologues, derivatives or reaction products. For example, copolymers based on 2-ethylhexyl acrylic ester have been found and n-butyl acrylate in reaction with the acrylic acid is advantageous. It is also possible Add resins or plasticizers to the adhesive.
Für eine sichere Verklebung werden in der Automobilindustrie Klebemassensysteme mit hoher Stabilität bezüglich UV-Belastung, Feuchtigkeit und thermischen Einflüssen verwendet. Hier zeigten sich ebenfalls derartige Acrylsäure-Copolymere als vorteilhaft. Adhesive systems are used in the automotive industry for secure bonding high stability with regard to UV exposure, moisture and thermal influences used. Such acrylic acid copolymers were also found to be advantageous here.
Von der zu beklebenden Oberflächen hängt die jeweils vorteilhafte Dicke des Material ab. Die Dicke richtet sich nach der Rauhigkeit, der Polarität und der gewünschten Festigkeit. Ferner kann das subjektive Einführungserlebnis des Gesamtaufbaus ausschlaggebend sein für die Einstellung der Dicke. Je nach Anforderung wurden Schichten zwischen 20 µm und 1200 µm eingestellt. The advantageous thickness of the material depends on the surface to be glued. The thickness depends on the roughness, the polarity and the desired strength. Furthermore, the subjective introduction experience of the overall structure can be decisive be for adjusting the thickness. Depending on the requirement, layers were between 20 µm and 1200 µm set.
Weiterhin kann zur Produktverbesserung ein Hilfsstoff beigemengt oder beigemischt werden. Hier lassen sich farbgebende Stoffe wie Pigmente, und/oder Füllstoffe, wie Mineralien oder auch Fasern beispielhaft nennen. Eine Verbesserung der Scherstabilität konnte durch Zugabe von Glasfasern oder Naturfasern erreicht werden. Ferner können auch Glasvoll- oder Glashohlkugel verabreicht werden. An additive can also be added or added to improve the product become. Coloring substances such as pigments and / or fillers such as Examples of minerals or fibers. An improvement in shear stability could be achieved by adding glass fibers or natural fibers. Can also full glass or hollow glass spheres can also be administered.
Die Herstellung von oben beschriebenden Schichten ist nach dem Stand der Technik bekannt. Hier zeigten sich handelsübliche Streich- und Düsensysteme als geeignet. Das Ausstreichen kann nicht nur aus der Schmelze, sondern auch als Lösungen, Emulsionen oder Dispersionen erreicht werden. The production of layers described above is state of the art known. Commercial coating and nozzle systems were found to be suitable here. The Spreading can not only from the melt, but also as solutions, emulsions or dispersions can be achieved.
Für besondere Anwendungen kann das Material auch partiell oder streifenförmig ausgestrichen werden. Hier ist der Raster- oder Siebdruck dann das geeignete Verfahren. For special applications, the material can also be partial or striped be crossed out. Screen or screen printing is the right choice here Method.
Das Austreichen auf einem abhäsiven Hilfsträger zeigt sich dann bevorzugt, wenn das Material erst zu einem späteren Zeitpunkt mit dem dekorativen, flexibelen Obermaterial kaschiert werden soll. The spreading on an abhesive subcarrier is preferred if that Only use the decorative, flexible upper material at a later date to be concealed.
Hier können, im Regelfall doppelseitig vorbehandelte, Papier-, Vlies-, Folien- oder Schaumbahnen zukaschiert und dann das Material auf sich selbst zur Rolle gewickelt werden. Here, as a rule, double-sided, paper, fleece, foil or Laminated foam sheets and then wound the material on itself into a roll become.
Für mache Anwendung ist eine reaktive Verknüpfung der Moleküle der Klebeschicht ebenfalls vorteilhaft.
